6,100 oz of Gold
Sonic Wells Recover 6,100 oz of Gold From a Heap Leach Pad
Boart Longyear used sonic sampling and targeted solution wells to identify and reactivate dry zones in a large Nevada heap leach pad, contributing to 6,100 ounces of recovered gold.
39 Shifts
Paste Fill Hole Reaches 2,152 ft in a One-Shot Pass
At Paulsens Gold Mine, Boart Longyear drilled a 656 m paste fill hole in one pass, reaching the target in 39 shifts and intersecting within 2.1 m of center.
<1% Hole Deviation
DTFR Water-Well Drilling Reaches Target Depth With Less Than 1% Deviation
Boart Longyear used dual-tube flooded reverse circulation drilling in the Pilbara to complete large-diameter mine water wells while controlling circulation, discharge water and hole deviation.
